My 14 month old male neutered sphynx has recently developed round red bumps on his belly and armpits. My vet says it's allergies. I haven't changed anything that I can think of around the house to cause this. Lately his eyes have been affected as well. One eyelid will start to swell so I give him the vet prescribed pedia pred and it improves within 24 hours. But just as the swelling starts to reduce, the other eyelid puffs up! How can this happen when he is getting the pedia pred? Does anyone have any experience with this kind of problem?
